This was an easy one because, having just started school, these little buggers are everywhere. Each child has multiple texts. Some are liked and some, not so liked. Here is Ms 17 yo with two of her current texts. Fortunately she likes both of them, well, at least the classes that go with them.
If you look closely, you might notice the rosary on top of the Psychology text. That, my dear friends, is to counter so much of the garbage that is in there :)
Check out Clan Donaldson and see what other type of texts are there.
